With reference to relevant data, the experiment is compared, and the main differences are briefly described as follows:
1 Morphological differences of original plants
Clover green: Climbing vines are grass. The surface of root tuber is dark brown, palmately compound leaves alternate, with 3 leaflets, sparse serrated leaf margin, glandular apex, hairless or hairless, and tendrils opposite. Cymes axillary; Petals 4, ovoid, with angular breakthrough at the top outside; Stamens 4, pistil 1, stigma 4-lobed, star-shaped. Berry is spherical, about 6mm in diameter, with 1 seed.
Soil: It is a tangled herb. The surface of root tuber is yellowish. Odd pinnate compound leaves alternate, with 3-7 leaflets, entire, short white hairs and stipules on both sides. Corolla butterfly, with flag flap, wing flap and keel flap; Stamens 9+ 1, pistils 1, thin style. Pods are flat, 5 ~ 8 cm long; There are many kinds of seeds.
2 differences in medicinal properties
Clover green: the root surface is brown to reddish brown, partially shriveled, with fibrous root marks and small tuberous protrusions or depressions; Some are smooth (made in Guangxi). The cross section is white or pale pink (red in Guangxi), and some radial vascular bundles can be seen. It's cool and nontoxic.
Soil: The root surface is yellowish, and some convex lenticels and punctate fibrous roots can be seen. The section is yellow and white, and the cambium ring and vascular bundle are not clear. Sexual equality, less toxicity.
3 microscope special film difference
Trifolium repens L.: The cross-sectional cortex is scattered with mucinous cells, with a diameter of 36 ~ 140μ m, containing needle-like crystal bundles of calcium oxalate, and some cortical cells contain brown substances; The phloem is narrow, the fibers are intermittent and slightly annular; The cambium ring and rays are clear; There are a little more vessels in xylem, accompanied by fibers and scattered mucinous cells containing needle-like crystal bundles. Powder grayish brown or light pink; Starch particles are 7 ~ 55 microns in diameter, with occasional composite particles, consisting of 2 ~ 3 fractions; Fiber wall thickness; There are many mucinous cells, round or oval, with a diameter of 36 ~ 1 10μ m, some of which are 200μm long, colorless and contain mucus, and some have needle-like crystal bundles of calcium oxalate. Needle crystals are bundled or dispersed, with a length of 45 ~ 100 micron, and cluster crystals are rare, with a diameter of 10 ~ 39 micron; The catheter has an edge hole.
Fig. 2: Mucous cells and brown substance are not found in the cross section; The phloem is extremely narrow, and the fibers are intermittently looped; The cambium ring and rays are not obvious; There are few xylem vessels, only a little more near the center and phloem, without fibers and mucinous cells. The powder is yellow and white; The diameter of starch granules is 5 ~ 20 microns, and there are many compound granules, most of which are composed of 2 ~ 3 fractions, and a few are 4 ~ 6 fractions. The phloem fiber wall is thin, some are teardrop-shaped, a few are spiny, and some can be seen with longitudinal or oblique texture; Mucous cells and needle-like crystal bundles were not found. Rare prism; Reticular vessels, rarely marginal, occasionally tracheids.
4 Application differences
Trifolium repens: There is no herbal record, but it is recorded in modern medical books or some drug standards (especially processing specifications). Its nature is cool and slightly bitter; Has the functions of clearing away heat and toxic materials, dispelling pathogenic wind and resolving phlegm, promoting blood circulation and relieving pain; Can be used for treating infantile high fever, tonsillitis, bronchitis, pneumonia, pharyngolaryngitis, hepatitis and viral meningitis.
Tuer: It was first seen in the Ming Dynasty's Herbal Medicine for Disaster Relief, but it has been used less recently. Sex is plain and sweet; Has the functions of detumescence, detoxification, expectorant and cough relieving; Indications: whooping cough, sore throat, breast abscess, furuncle and snake bite.
Obviously, there is only one word difference between clover (golden thread hanging gourd) and golden thread hanging gourd, but they are completely different plants, and patients must not eat them by mistake.
